The invention provides a path trajectory planning method, which comprises the steps of determining a preset trajectory point sequence of a target vehicle, the preset trajectory point sequence being used for inputting a double-loop iterative algorithm as an initial hot start item; determining a nonlinear function of SV speed limit, wherein the nonlinear function of SV speed limit is used for calculating a speed constraint condition of a double-loop iterative algorithm; and starting a double-loop iterative algorithm to carry out optimization solution on the preset track point sequence so as to output a target path track point sequence. According to the method, the speed of solving a nonlinear planning problem is increased and the path trajectory planning time is shortened by constructing a double-loop iterative algorithm framework.
